A pizza parlor uses square prisms for their pizza boxes. Due to the crust rising, the height of their boxes is always 2 inches. Additionally, the volume of the pizza box must be 450 cubic inches to fit their standard-sized pizza. A worker determined that the equation below could be used to find the side length, x, of the box needed to reach that volume.

Answers

We are to find the side length of the box

Volume = Length * Breadth * Height

Volume of box = 450 cubic inches

Height of box = 2 inches

Length of box = x

Since it is a square prism, Breadth = Length = x

Therefore,

Volume = Length * Breadth * Height

⇒ 450 = 2 * x * x

⇒ 450 = 2x²

⇒ 2x² = 450

Divide the equation by 2

2x²/2 = 450/2

x² = 225

⇒√x² = √225

x = 15

The side length of the box is 15 inches

Answer:

The solutions are -15 and 15, but only 15 is a reasonable side length.

What is the sum of the arithmetic series below? Use the formula for the sum of an arithmetic series.

Answers

Answer: The required sum is 504.

Step-by-step explanation: We are given to find the sum of the following arithmetic series using the formula for the sum of an arithmetic series :

[tex]\sum_{i=1}^{18}(2i+9).[/tex]

The given arithmetic series can be written, in expanded form, as follows :

[tex]11+13+15+17+~.~.~.~+43+45.[/tex]

We know that

the sum of first n terms of an arithmetic series with first term a and common difference d is given by

[tex]S=\dfrac{n}{2}\{2a+(n-1)d\}.[/tex]

In the given series, a = 11 and d = 13 - 11 = 15 - 13 = . . . =2.

Therefore, the sum up to 18 terms will be

[tex]S_{18}=\dfrac{18}{2}\{2\times 11+(18-1)\times2\}=9(22+34)=9\times56=504.[/tex]

Thus, the required sum is 504.

The sum of the arithmetic series ∑₁¹⁸(2i + 9) using the arithmetic series formula is 504.

To find what is the sum of the arithmetic series ∑₁¹⁸(2i + 9) below using the formula for the sum of an arithmetic series, we proceed as follows

The formula for the sum of therms of an arithmetic series is given by

Sₙ = n/2(a + Tₙ) where

n = number of termsa = first term and Tₙ = last term

Now, since we have that arithmetic series, ∑₁¹⁸(2i + 9), the nth terms is U = 2i + 9

Now, the first term is when i = 1.

So, U₁ = a = 2(1) + 9

= 2 + 9

= 11

Also, the last term is when i = 18

So, U₁₈ = T₁₈ = 2(18) + 9

= 36 + 9

= 45

So, the sum of terms Sₙ is when n = 18

S₁₈ = 18/2(11 + 45)

= 9(56)

= 504

B).6
C).7
D).12

Answers

There are 12 ways that Jackson can order his hot cocoa.
So, the answer is 12.

i hope this helps :)

There are 12 ways Jackson can order his hot cocoa by choosing from three flavors, two mug sizes, and the option of adding marshmallows. Option D is correct,

To find the total number of ways Jackson can order his hot cocoa, we need to consider all the possible combinations of choices he has.

1. Flavor: Jackson has 3 options: milk chocolate, dark chocolate, or chocolate mint flavor.

2. Mug Size: Jackson has 2 options: small or large mug.

3. Marshmallows: Jackson has 2 options: with or without marshmallows.

To find the total number of combinations, we multiply the number of options for each choice:

[tex]\[ \text{Total combinations} = \text{Number of options for flavor} \times \text{Number of options for mug size} \times \text{Number of options for marshmallows} \]\[ \text{Total combinations} = 3 \times 2 \times 2 \]\[ \text{Total combinations} = 12 \][/tex]

So, there are 12 ways Jackson can order his hot cocoa. Therefore, the correct answer is option D) 12.

Engineers must consider the breadths of male heads when designing motorcycle helmets. men have head breadths that are normally distributed with a mean of 6.0 in and a standard deviation of 1.0 in. (based on anthropometric survey data from gordon, churchill, et al.). if one male is randomly selected, find the probability that his head breadth is less than 6.2 in. use 4 decimals for your answer.

Answers

Answer: 0.9772 (the answer above wasn't the right one;)

Using z-score formula, the probability that a male's head breadth is less than 6.2 inches, would be approximately 57.9261%.

What is z-score formula?

When you have multiple samples and want to describe the standard deviation of those sample means (the standard error), you would use this z score formula:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

This z-score will tell you how many standard errors there are between the sample mean and the population mean.

We have been given that men have head breadths that are normally distributed with a mean of 6.0 inches and a standard deviation of 1.0 inches. We are asked to find the probability that a man's breadth is less than 6.2 inches.

First of all, we will find z-score corresponding to sample score of 6.2 as:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

where,

z = Z-score,

x = Sample score,

[tex]\mu[/tex] = Mean,

[tex]\sigma[/tex] = Standard deviation.

Upon substituting our given values in z-score formula, we will get:

[tex]z=\frac{6.2-6.0}{1.0}[/tex]

[tex]z=\frac{0.2}{1.0}[/tex]

z = 0.2

Now, we need to find the probability that a z-score is less than 0.2.

Using normal distribution table, we will get:

P(z < 0.2) = 0.57926

0.579261 ≈ 57.9261 %

Therefore, the probability that a male's head breadth is less than 6.2 inches, would be approximately 57.9261%.

A map of Scotland is drawn to scale of 1:325,000.
how many CM on the map would show 65KM?

Answers

1:325,000 means 1 cm shows 325,000 cm,
converted to metres 1 cm shows 3250 metres
converted to km 1 cm shows 3.25 km

so to show 65 km
65/3.25 which gives 20 cm

Final answer:

On a map of Scotland, drawn to the scale of 1:325,000, 65 KM of real-world distance will be represented by 20 cm on the map.

Explanation:

The question pertains to the scale existing on a map. A map scale enables us to convert the measurements on the map into the corresponding real-world distances. Here, we have a map of Scotland that is drawn to the scale of 1:325,000. This signifies that 1 cm on the map equates to 325,000 cm in reality.

To ascertain how many cm on the map would represent 65 KM, we first need to convert 65 KM into cm. As we know, 1 KM is equal to 100,000 cm. Therefore, 65 KM will be equivalent to 65 * 100,000 = 6,500,000 cm.

Now, we divide the real-world cm (6,500,000 cm) by the scale (325,000), which gives us the cm on the map. Thus, 6,500,000 cm / 325,000 = 20 cm

So, on this map, 65 KM will be denoted by 20 cm.

I think A does 600 and B does 412.50

Contractor A estimated a job would cost $54,000 to complete in 90 days.

Per day charge of Contractor A = $54,000 / 90 = $ 600 / day

Contractor B estimated he could complete the same job for $49,500 in 120 days.

Per day charge of Contractor A = $49,500 / 90 = $ 412.50 / day

Therefore, Contractor A charges $ 600 per day and contractor B charges $412.50 per day.

(n+3)/(2n-6):(n+3)/(3n-9)=(n+3)/(2(n-3))×(3(n-3))/(n+3)=3/2

ANSWER
The quotient simplifies to
[tex] \frac{3}{2} [/tex]

EXPLANATION

We want to find the quotient:

[tex] \frac{n + 3}{2n - 6} \div \frac{n + 3}{3n - 9} [/tex]

We need to multiply the first fraction by the reciprocal of the second fraction to obtain,

[tex]\Rightarrow \frac{n + 3}{2n - 6} \div \frac{n + 3}{3n - 9} = \frac{n + 3}{2n - 6} \times \frac{3n - 9}{n + 3} [/tex]

We now factor to obtain,

[tex]\Rightarrow\frac{n + 3}{2n - 6} \div \frac{n + 3}{3n - 9} = \frac{n + 3}{2(n - 3)} \times \frac{3(n - 3)}{n + 3} [/tex]

We cancel out common factors to obtain,

[tex] \Rightarrow\frac{n + 3}{2n - 6} \div \frac{n + 3}{3n - 9} = \frac{1}{2} \times \frac{3}{1} [/tex]

This finally gives us,

[tex] \frac{n + 3}{2n - 6} \div \frac{n + 3}{3n - 9} = \frac{3}{2} [/tex]

In order to survive, organisms must maintain stable conditions in their bodies, even though their external environments are always changing.

For example, humans need to maintain an internal temperature around 37°C. Blood needs to have a pH around 7.4 and an oxygen saturation close to 100%.

What needs to happen in order to maintain these conditions?

A) Organ systems must interact with one another.
B) Organisms must be at rest.
C) Genes must be altered each time cells replicate.
D) All of these.
